To you give you an idea; for me details that include buffing steps start at $300 and that's, more or less, a one stage buffing job which I will lightly cut and polish in one stage. The first level of paint correction that I offer starts as a 2 step which is is a light/medium cut and then a light/medium polish, starts at $400. And it only goes up from there, which is an hourly rate of $60/hr. We did a Lambo Countach with heavy paint correction which was close to a 6 step process including sealants and full exterior/interior detail; that came out to $1500. If your work compliments your price, you can almost charge whatever you want.... there are plenty of detailing company websites, from amateurs to professionals, that you'll be able to get a better idea of what you can charge.
